BUILDING-TIE.

1 Specification of Letters Patent.

Application filed June 24, 1913. Serial No. 775,499..

To all whom it may concern:

Be it known that I, CHARLES B. HARP, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Building-Tie, of which thefollowing is a specification.

This invention relates to a tie adapted for securing together parts of abuilding, particularly the parts of a wall structure consisting of innerand outer slabs and a stud. In addition to this function the device alsoserves to form a shoe which becomes a part of the end of the stud andforms a bearing plate on the end ofthe stud, preventing the corners ofthe stud from crumbling.

Ina previous application of mine filed August 2nd, 1912, Serial No.712,881, I have I have shown a metallic end plate for a shown a tiewhich accomplishes the functions of fastening the parts of the wall andthe stud together, but does not protect the corners of the stud exceptincidentally and only partially. In another application of mine filedMay 22nd, 1913, Serial No. 769,311,

building stud which is a part of the stud and which protects the cornersthereof from crumbling, but such latter plate does not act in any way toform a tie to lock the inner and outer slabs to the stud.

The object of the present invention is to provide a device which issoconstructed that it will produce the results produced by both of theforegoing inventions. Thus in one device I obtain the results which toobtain heretofore have required three devices, viz., the protectingplate for the end of the stud and two ties to extend across on oppositesides of the stud to unite the inner and outer slabs with the stud. Inthe present invention, I do not form the device of a single piece ofmetal, but construct it as a built up unit consisting of five pieces.This requires but a trifle more material than would be required inconstructing it of a single piece of material, and although it is abuilt up unit of several pieces, the device as a unit, or the amount ofmaterial in the aggregate, is about one-third of the amount rerequiredto obtain the results of the two former inventions referred to. Inaddition to these advantages, the device is better in other ways. Itgives a stronger interlocking, because, the center portion of it ismolded in the stud itself, and it is so constructed 7 edge that itenablesthe anchoring of a joist and '1 permits the formation of a selfreleasing connection and is also capable of affording a connection forreinforcing rods of a concrete structure.

Other advantages. will be brought out in the following description.

Referring to the drawings, Figure 1 is a perspective view of theupperportion of a stud with adjacent portions of outer and inner slabs allinterlocked together by'the tie. Fig. 2 is a perspective of one of thewings in detail. Fig. 3 is a perspective View of the center piece indetail. perspective view of the corner of a stud, showing the manner ofknocking off the corners to" enable the attachment of the tie. Fig. 5 isa perspectiveof a portion of the wall and a joist secured-to the tiewith a self releasing anchor. Fig. 6 is a perspective view of a portionof a wall with a part broken away, showing the use of atie'where aconcrete girder with a metal reinforcement is employed, secured to thetie. Fig. 7 is an inverted plan of the built up unit.

The unit comprises. a center piece 1 at the and is formed with a.plurality of downturned claws 2, the lower edges of which are slightlyinbent as at 3 to firmly interlock in. the stud 4;. At an intermediatepoint claws 5 are formed by bending down a portion of the plate. Notches6 are formed at the inner edges of the claws 2 and notches 7 are formedat the inner edges offthe be molded on the end of the stud 4:,fso thatthe wings 8 are permanently embedded in the stud and the claws 2 and 5also perma- 1 nently embedded and locked therein The plate 1 near eachend is formed with trans verse corrugations 10. These corrugations actto key the mortar and produce a perfect shearing which prevents themortar in "the joint from slipping.

Secured to each end of the plate 1 is a pair of wings 11, each wing 11having upturned ears 12 and downturned cars 13. The downturned ears 13have inbent edges 14 which interlock in the notches 6 and the wings 11are attached by slipping them vertically down, so that the inbent edges14 slide downwardly in the notches 6, thus interlocking the parts of theunit inthe manner clearly shown in Fig. 7. The wings 11 fit over theinner and outer slabs 15 and 16,

the ears 13 of each wing fitting on opposite sides of the slabs, whilethe innermost wings 13 also fit over the outer wings 2 of the plate 1.The upturned cars 12 of the wings 11 engage inner and outer faces of thenext higher tier of irmer and outer slabs; In

order to assemble the wings 11 it is neces-' sary to chip out thecorners at 17 of the stud 4 ,as indicated in Fig. 4:, to permit the clawforations 18. This enables one of the claws to be bent up at an angle asshown in Fig.

5 to receive the end 19 ofa rod 20 which is secured to a joist 21 in anydesired manner,

as for example, by staples 22 with the end '23 of the rod 20 bent anddriven into the joist. This forms a self releasingjoist anchor which, ifthe joist burns, will allow the joist to release itself fromthe wall.Thus if the joist burns, its inner portion will swing down, causing thejoist to fulcrum on the inner edge of the inner slab in Fig.5, and'asthe joist thus swings down it will draw the "with means for engaging astud, wings deend 19 down out of the. hole in the claw 13 and allow thejoist to fall without injuring the wall.

Fig. 6 indicates how one of the perforated claws may serve for theattachment of a reinforcing rod 24. In this view I have shown a concretegirder 25 which is reinforced by the rod 24, the latter being bentandextended through one of the perforated claws.

Each of the wings 11-is preferably provided with a central perforation26 to allow the mortar to pass therethrough and unite with theslab.

What I claim is:

1. A building ti e for securing wall members together comprising a platehaving depending claws thereon to engage with the inner faces of a wallmember, and detachable wings overlapping said plate and formed withupwardly extending ears to engage a wall member, said wing being alsoformed with downwardly extending ears to closely engage the outer facesof the claws whereby the wings are rigidly secured against angular andlongitudinal movementwith respect to the plate.

2. In combination, a center plate, means for anchoring said center plateto the end of a stud, and transversely slidable detach- .able wings ateach'end of the center plate,

said wings being provided with means for engaging inner and outer wallmen1bers.'

3. In combination a center plate "wlth transverse corrugations at eachend, and detachable wings at each end, said center plate being formedwith means for anchor in'g it to a stud, said wings being provided withmeans for engaging wall members.

4. In combination a center plate with end claws and intermediate'clawsadapted to engage a stud, detachable wings at each end of the centerplate projecting laterally therefrom, and each of said wings havingclaws adapted to engage inner and outer wall slabs.

5. In combination a center plate with end claws and intermediate clawsadapted to engage a stud, detachable wings-at each end of the centerplate projecting laterally therefrom, and each of said wings havingclaws adapted .to engage inner and outer wall slabs, said claws havingperforations for the attachment of joist anchoring rods.

6. In combination a center plate provided claws.

8.. In combination, a center plate provided with downturned clawsadapted to anchor a plate to a stud, and wings detachably secured to theends of said plate, each of said wings having upturned claws anddownturned claws, each of said wings having a perforation for thepassage of mortar.

In testimony whereof, I have hereunto set my hand at lLos Angeles,California this 18th day of June 1913.
